c# - Windows 10 Iot/UWP 上的 Azure 存储库客户端？

Question

Windows 10 Iot-Core/UWP (RPi) 似乎不支持 Azure 存储客户端。不过，我将它用于 Blob，并且它对于表也可以正常工作。现在，更新到最新的稳定版本(以及-pre，尝试了两者)后，对表的访问挂起在

await table.ExecuteQuerySegmentedAsync(query, new TableContinuationToken());

我徒劳地寻找一种使其同步的方法，这至少可以帮助我调试它。我还想知道其他人当前的成功以及在 IoT-Core (RPi) 上使用 Azure 存储客户端的“独家报道”。

更新:如下扩展了 RequestOptions，我的简单调用也如下所示。我仔细检查了连接字符串、表访问(来自其他工具)和帐户。他们在其他地方都工作得很好。我还将 VStudio2015 远程调试中遇到的异常粘贴到 IoT-Core RaspberryPi 最新版本中。

        // Setup the table container
        // connectString looks fine, works fine elsewhere: http for debug instead of https 
        var connectionString = @"DefaultEndpointsProtocol=http;AccountName=myaccount;AccountKey=EUybijab+WHATEVERDzYubKGADwjf/6k5IuoRVgPMMqMez0gb07/dfAv9Qj1/v7NkstGAygWNab07q6FhNBQ==";

        var cloudStorageAccount = CloudStorageAccount.Parse(connectionString);
        CloudTableClient cloudTableClient = cloudStorageAccount.CreateCloudTableClient();
        cloudTable = cloudTableClient.GetTableReference(appSettings.AzureStorageOeConfigTableName);
        //never returns var x = await cloudTable.CreateIfNotExistsAsync();

        // Simplest query to existing small table
        var pkey = "b8-27-eb-86-5d-4d";
        var rkey = "0000000013505717";
        var tstOp = TableOperation.Retrieve(pkey, rkey);
        var requestOptions = new TableRequestOptions
        {
            PayloadFormat = TablePayloadFormat.JsonFullMetadata,
            LocationMode = LocationMode.PrimaryThenSecondary,
            RetryPolicy = new ExponentialRetry(),
            ServerTimeout = TimeSpan.FromMinutes(2)
        };
        // Throws exceptions shown below.
        var tst1 = await table.ExecuteAsync(tstOp, requestOptions, null);

异常(exception):对我的测试代码有什么想法或修改吗？

是的，遗憾的是，存储尚不支持 UWP 应用，因为 UWP 平台中存在一个错误，会导致身份验证出现问题。我们正在等待 UWP 团队的修复。谢谢!
